Color Constants

On radios with color display, a color may be added to the flags described above.

There are two types of color constants: one that is an index into a table holding a palette of theme colors, and one that is just a color.

Indexed colors

These are the theme colors plus CUSTOM_COLOR, and they can be changed with the function lcd.setColor(color_index, color). Please note: if an indexed color is changed, then it changes everywhere that it is used. For the theme colors, this is not only in other widgets, but everywhere throughout the radio's user interface!
